Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed May 12, 1903. Renewed September 11 1905. Serial No. 278,039.

, of successive battery-cells of a storage battery which makes the connection of the respective terminals. positive and ne ative, more certain and fixed, and also enab es the connection between the positive and negative'terminals of successive cells to be readily disconnected for substitution and repair.

I will first describe the embodiment of my invention illustrated in the accompanying drawings and then point out the invention in the claims.

In the drawings, Figure 1 is an end view of the plates of a battery-cell, the positive battery-terminal, and the connection of the positive plates to the positive battery-terminal. Fig. 2 is a section on the line 2 2,'Fig. 1; Fi 3 is an end view of the plates of a battery-eel the negative battery-terminal, and the connection of the negative plates to the. negative battery-terminal. Fig. 4 is a section on the line 4 4, Fig. 3. Fig. 5 is a top plan view of a three-cell battery set up, showing terminal connections. Fig. 6 is a sectional view of pin and head, showing modified construction with cable wound directly upon pin.

A A are a series of positive plates of a storage-battery cell having the terminals a.

B B are a series of negative plates of a storage-battery cell having the terminals 6.

Speaking first of the positive-plate terminal connections of a batter 2, C is a cast-lead termina plate having the projection c, in which is secured during casting the pin 0, whose head 0 extends above the projection. The terminals a are inserted into the mold during the castin of the plate C and while the plate is still fiui and are cast or welded onto the fiat surface of said plate. The pin 0 has upon it the thimble O. The connecting-wires of a cable E are bent directly around the thimble C to form a loop,

cell, Figs. 1 and and lead is cast around the loop, thus embedding the cable or the cables surrounding the thimble in lead havin the socketed projection 0 The head a o the pin 0 isv placed in this loop and is secured by cast-lead poured on the top.

In Fig. 6 the thimble C is dispensed with and the cable or cables bent directly around the in-head.

T e negative terminals 5 are connected to a cast-lead terminal plate B (see Figs. 3 and 4) in like manner as are connected to the cast-lead terminal plate C. In the projection b of this plate is likewise secured a pin 6, which, unlike the pin 0, is threaded at its top. The connecting-wires the positive terminals a of the cable E are alike with reference to the positive pole, either bent into a loop or surrounding a thimble G, the loop or the thimble being embedded in lead forming a casting G, having the projecting socket G The pin 72 passes through the loop and is secured against the lead surface G by the nut G In either case instead of wire cable the terminal conductor may be of lead.

In assembling up the cells of a battery the following is the method: The positive and negative plate terminals of a given cell are connected to their corresponding plate and respectively to the ositive and negative terminals of a cell, as escribed. Over each cell is then placed the rubber cover H, Fig. 5, which is orificedto ass over the battery-terminals. In each p ate H is a central orifice provided with a cap or cover It, the orifice being for the purpose of admitting the battery liquid. The cable E is then attached as described, one end to the positive terminal of one cell, the other end to the negative terminal of the other cell. By this arrangement the plate-terminals of a connected with certainty to the corresponding cell-terminals, and the connection between battery-cells is made in such a way as to readily enable. the connections to be changed when it is necessary to cut out a cell or change the arrangement.
